Patented Oct. 11, 1932 UNITED STATES PATENT OFFICE ADOLPH e. LOTTER, orMILWAUKEE, WISCONSIN, ASSIGNOR ,TO H. 0. MILLER 00... or

MILWAUKEE, WISCONSIN a l RING BINDER Application filed November 18,1927. Serial No. 234,107.

This invention relates to ring binders.

In ring binders as heretofore constructed it is the usual practice toprovide a spring clip extending the full length of the binder andprovided with movable members carry ing the half ringsections so thatthey may be either snapped open or'snapped closed.

Other types of binders have been proposed, such as shown in thecopending application of H. C. Miller, for visible record system, filedin the United States Patent Ofiice, De-

cember 10, 1925, Serial No. 74,523, and now matured into Patent No.1,787,755. In this latter type of binder, means have been provided forsliding one set of half ring sec.- tions with reference to the other setthereof. However, this form of binder is adapted for a direct inwardmotion of the ring sections and does not employ the spring type, asdescribed immediately above.

This invention is designed to provide a spring type of ring binder whichis so constructed that the half ring sections may be shiftedlongitudinally soas to bodily shift the sheets carried thereby one-halfspace with reference to the opposite rings, thus permitting the sheetsto be turned over onto the opposite rings and transferred in a shiftedposition, as described in cletailin the above Further objects are toprovide a very simple type of spring binder which is so constructed thatthe shiftable half ring sections may be very readily attached theretoand permitted to shift when the binder is open and to provide aconstruction which is easilyproduced, which is easy to operate, andwhich is reliable in operation. I

An embodiment of the invention is shown in the accompanying drawings inwhich':'

Figure 1 is a view of the central portion of the binder with the covers,which are only partially shown, laid out flat;

Figure 2 is an end view of the structure shown in Figure 1;

Figure 3 is a detail showing the manner in which the back is fastened tothe spring portion of the binder;

.0 Figure 4 is a view corresponding to Figure 1 showing the rings openand shifted-a half space; v

Figure 5 is a sectional view on the'line 55 of Figure 4; a

Figure 6 is a detail of the endv structure of the binder showing theclip for retaining the slide in either of two positions. 1

Referring to the drawings, it will be seen that the binder comprises anarcuate spring member 1 (see Figures 2 and 5) which is pro-. vided withinturned ends 2 and 3. The inturned ends receive the rocking plates 4and 5. One of the rocking plates, "for instance, the plate 5, hasrigidly attached thereto the ring carrying plate 6, The other ringcarrying plate 7 is slidablycarried by the plate 4,as will The plate 6carries the hereinafter appear. half ring sections 8 and the plate 7carries the half ring sections 9. The binderis adapted to be snappedopen or closedby pulling upon the half ring sections 8 and 9. There is atoggle action secured byfithe arcuate spring land the plates 4 and 5, asis obvious from reference to Figures 2 and 4. Prefstuds 11 secured tothe plate 4, thus permit-- ting free longitudinal sliding of the stripor plate 7. This plate 7 is provided with a manipulating handle 12adjacent one end and is provided with an aperture 13 adjacent the otherend. The aperture 13'is adapted to receive the rounded projectingportion 14 of a spring 15 secured to the plate 4, as shown particularlyin Figure 6. This engagement of the a erture and projecting portion 14is secure when the plate 7 is slid upwarde ly as viewed in Figure 4.When the plate 7 is slid downwardly, as shown in Figure 1,

the projecting portion 14 snaps upwardly beyond the end of the plate 7and thus temporarily locks it in closed position. The plates 4 and 5 areeach provided with notches which receive the contracted portions ofbeaded studs 16, as shown in Figure 5.-

. the ordinary capacity of a spring type ring:

These headed studs constitute therefor the bearing portions of theplates 4i and 5 and permit the toggle action referred to, and as bestshown in Figure 5, the depth and width of the annular channel formingthe contracted portion of each stud 16 is such that when the binder isopen as illustrated in Figure 5, the edges of the notches in which.

thecontracted portions of the headed studs are-received, co-act with thetop and bottom of the annular channels forming said contracted portionsto prevent movement of the plates 4 and 5 beyond a predetermined degreeand to thus retain the plates assembled with the spring back.

A, very simple means is thus provided whereby the spring ring typebinder may be used for shifting the recordL sheets as heretoforedescribed without any cumbersome construction whatsoever, but instead ina very cheap; and simple manner.

Further it. is to be noted that the additional fatuires cooperate withthe ring type bineer to secure the shiftable features without however,sacrificing any of the securities of attachment of the parts or theinterlocking of the half ring sections.v The spring stop 14. arrests themotion of the shiftablev plate 7 carrying one half of the ring sectionsat either of two predetermined points to thus insurecorrectspacingor-correct registry of the rings, so that the binder maybe used inbinder and: also may be used for shifting the sheets.-

It; is to be noted also that this binder may be". very readily attachedto a back by the construction illustrated. inFigures 1. and TlHS'lSsecured by PI'OVlCllI-l-g' an extra plate 17 having upstruck tongues: 18pas through slots 19 in the bottom. of the spring. 1 and clampeddownwardly in place. These tongues passthrouglrv the back. 20 and" theen;- tire back is covered with suitable fabric in zaccordance with theusual practice, such fabric being omitted from Figure 3 for the sakeofclearness.

These tongues are preferably made of triangular shape, as shownparticularly in Fig.-

sure 1, and the plates 5- and 6, andv l and. 7,

not only has the characteristics of the springtype binder but alsoprovides for the shifting ofone set of prongs with reference to theotherset of prongs.
